In a collision involving a front-wheel drive vehicle, what condition indicates that the outer CV-joint may need replacement?

The presence of a torn boot on the outer CV-joint is a significant indicator that it may need replacement. The CV-joint, or constant velocity joint, is crucial for transferring torque from the vehicle’s transmission to the wheels while allowing the suspension to move. The boot serves as a protective cover for the joint, containing lubrication and keeping dirt and debris out. When the boot is torn, it allows grease to escape and contaminants to enter, which can lead to joint failure over time.

This condition is critical because if the CV-joint lacks proper lubrication or is compromised by dirt and moisture, it will deteriorate quickly, leading to more severe issues such as complete joint failure that might result in loss of vehicle control. Thus, identifying a torn boot warrants immediate inspection and potentially replacing the CV-joint to ensure safe vehicle operation and prevent further damage.
